Pulmonary nocardiosis is an infrequent but severe infection due to the microorganism, Nocardia spp, which may behave as both an opportunists and as a primary pathogens. Usually nocardiosis is found in patients under immunosuppressive regimens for organ transplans, chemotherapy for a malignancy and corticosteroids. The experience of pulmonary nocardiosis in the medical literature is limited to just case reports, with a few series including extrapulmonary nocardiosis. It is believed that the incidence of this infection has been increasing since 1960. The diagnosis is difficult because of the nonspecific clinical manifestations, the lack of laboratory evidence, and the non-specific radiographic findings. Here, we report a case of pulmonary nocardiasis in a 66 year-old patient with alcoholic liver cirrhosis who has suffered from acutely developed dyspnea and general edema. The nocardia species. was cultured from a specimen obtained by a percutaneous transthoracic needle biopsy.
